Compliance – Proven Questions from Certified Professionals –
Detailed Rationales for Every Answer – Pass the CESSWI
Certification on Your First Attempt
Erosion - answer process in which, by the
actions of wind and/or water, soil particles
detached and transported
Sediment - answer eroded material
suspended in wind or water
Sedimentation - answer deposition of
eroded material
Types of Erosion - answer splash
,sheet
rill
gully
channel
Splash erosion - answer raindrop impact
energy is enough to dislodge surface
sediments
sheet erosion - answer caused by rain
splash detaching soil particles lifting them
up and removing them by shallow "sheets"
of water flowing down the sloped soil
surface
,Rill Erosion - answer as flow concentrates,
small channels begin to form in the soil
surface
Gully Erosion - answer Formed when runoff
cuts rills deeper and wider or when flows
from several rills come together and form a
large channels
Channel Erosion - answer may become
unstable due to increased flows or changes
in upstream sediment load
Natural erosion - answer generally
considered due to the influences of climate
on the surface of the earth
, Accelerated erosion - answer natural
erosion plus human activities
What problems can accelerated erosion
cause? - answer Unrestricted development
removal of surface cover
increased imperviousness
poor stewardship
Problems associated with construction
related erosion - answer problems for down
slope property owners
nuisance problems on streets
clog streams and storm drains
increased turbidity downstream
cover sensitive habitat with sediment
